Description

Die-cutting mechanism and die-cutting machine

Technical Field

The invention relates to the technical field of die cutting equipment, in particular to a die cutting mechanism and a die cutting machine.

Background

During label production, it is sometimes necessary to cut a perforation in the label, and the equipment used to accomplish this step is typically a die cutter that cuts the perforation in the label by an up and down moving cutter without damaging the base paper of the label.

However, since the cutter only cuts the perforation and does not strip the excess material in the perforation, the excess material still adheres to the perforation, and the excess material in the perforation needs to be manually torn off after the label is produced.

The above prior art solutions have the following drawbacks: the excess material in the perforation on the label is torn off manually, on one hand, more manpower is consumed, on the other hand, the excess material is torn off manually from the perforation, the tearing efficiency is low, and therefore improvement is needed.

Disclosure of Invention

In view of the defects in the prior art, an object of the present invention is to provide a die cutting mechanism, which can cut a perforation on a label and tear off the excess material in the perforation, thereby reducing the use of manpower and improving the tearing efficiency.

The above object of the present invention is achieved by the following technical solutions:

the utility model provides a die-cutting mechanism, includes the mounting panel, fixedly on the mounting panel be provided with the die-cutting rule, and the die-cutting rule is the annular, and the blade setting of die-cutting rule is in the port department of self one end to the blade of die-cutting rule is acute angle, the contained angle that the die-cutting rule blade exceeds mounting panel side surface with the horizontal plane one-tenth.

By adopting the technical scheme, the installation plate provides a stable installation position for the die-cutting rule; because the included angle formed by the cutting edge of the die-cutting rule and the horizontal plane is an acute angle, the cutting edge of the die-cutting rule is retracted inwards, after the die-cutting rule cuts the perforation, the cutting edge of the die-cutting rule can scoop up the excess material in the perforation, so that the excess material leaves the perforation, and at the moment, the excess material in the perforation does not need to be torn off manually after the label is subjected to die cutting, so that the use of operation manpower is reduced, and the tearing efficiency is improved; and because the clout is close to there is glue on the body paper side surface, along with a clout is taken up, when another clout was taken up in the follow-up area of die-cutting rule, a previous clout can also stick a back clout, helps promoting the effect of tearing the clout.

The invention can be further configured in a preferred example that a fixing piece is fixedly arranged on the surface of one side of the mounting plate, which is far away from the cutting edge of the die-cutting rule, the fixing piece comprises a connecting plate and a fixing plate, the fixing plate is arranged at the surface of one side of the connecting plate, the fixing plate is fixedly connected with the connecting plate, and the mounting plate is fixedly arranged on the surface of one side of the fixing plate, which is far away from the connecting plate; a material receiving space is arranged between the fixed plate and the connecting plate, a material conveying hole is formed in the side wall, close to one side of the fixed plate, of the material receiving space, and one end port, far away from the material receiving space, of the material conveying hole extends into a ring hole in the die cutting rule.
